swimming poolBlog Entry:
A swimming pool has 4 water taps. The first tap alone will fill the pool with water in 1 hour. The 2nd in 45 min, the 3rd in 30 min and the 4th in 15 min.
When all 4 water taps are open, how long it last to fill the pool?

Mr. GaussBlog Entry:
There was once a little boy in school, first class. One day his lazy teacher said to the class: Add the numbers from 1 to 100. Who is ready can go home ( 1 2 3 .. 99 100). The teacher laid back in his chair and began to read a newspaper, thinking it would last long till the kids solve this. But, miricale, the youngest in the class, Karl-Friedrich, said after a few minutes: 5050. How he did it so fast?
